GAS-LIBERATING HEADER FOR STEAM-CONDENSING COILS.

Specification of Letters Patent.

Application filed January 18, 1909. Serial No. 473,013.

To all whom it may concern:

. Be it known that I, WILLIAM F. Pxnanrsn, a citizen of the UnitedStates, residing at Leavenworth, in the county of Leavenworth and Stateof Kansas, have invented certain new and useful Improvements inGas-Liberating Headers for Steam-Condensin Coils, of which the followingis a specificatlon.

This invention relates to steam condensing coils and more especially togas-liberating headers for such coils, and my object is to produce aheader equipped with a valve adapted to open under a pressure in theheader, greater than atmospheric pressure, and close as the pressurefalls to that of the atmosphere.

A further object. is to produce a header embodying a series of chamberseach provided with a gas-liberating passage con trolled by a valve andso connected by the pipes of the coil that the gas arising from thesteam circulated throu h the coil, shall have as many opportunitiestoescape as there are chambers, so that the ice eventually produced,shall be free from the vegetable taste and odor ordinarily perceptiblein ice made from water from which the vegetable gases have not beenwithdrawn.

A still further object is to produce a header for circulating coils, ofsimple, strong, durable and inexpensive construction.

WVith these objects in view the invention consists in certain novel andpeculiar features of construction and organization as hereinafterdescribed and claimed; and in order that it may be fully understoodreference is to be had to the accompanying drawing, in which,

'Figure 1, represents a coil equipped with a single header shown incentral vertical section. Fig. 2, is an inner face view of the header.Fig. 3, is a central vertical section of one of the valves.

In the said drawing, 1 indicates a header provided by preference with apair of supporting legs 2 and divided by horizontal partitions 3 into aplurality of superposed chambers 4, 5 and 6, the upper chamber 4 havinga tubular portion 7 extending through the end, and forming a passage 8.It is also provided in its upper side with a passage 9 and with a pairof threaded openin s 10 and 11 in the vertical plane of and belowpassage 8. Chamber 5 is likewise provided with a pair of threadedopenings 12 and 13 in the vertical plane of and below threaded openings10 and 11 and with a passage 14 extending obliquely upward and outwardfrom its upper end. Chamber 6 is also provided with a pair of threadedopenings 15 and 16 in the vertical plane of the other threaded openingsmentioned, and with a passage 17 extending obliquely upward and outwardfrom its upper end.

A series of valves 18, 19 and 20 control passages 9, 14 and 17respectively, each of said valves consisting of an externally threadedtubular casing or plug 21 provided with an enlargement or head 22,having one or more passages 23 communicating with the interior of thecasing. The lower or inner end of the casing is provided with avalveseat opening 24, and outward of or above the enlargement the casingis provided with a perforated diaphragm 25.

26 is a screw-cap closing the outer end of the casing and providedcentrally with a socket 27 receiving the outer or upper end of anexpansion spring 28 seated at its opposite end in a socket 29 in theouter end of the valve-plug 30 and holding said valveplug normally uponand closing valve-seat opening 24, the valve-plug being of less diameterthan the chamber of the casing and fitting slidingly at its upper orouter end in the perforated diaphragm.

31, 32, 33, 34, 35, 36, 37 and 38 indicate pipes of the steam coil, thefirst-named pipe being mounted in passage 8, the second being screwedinto threaded opening 10, the third into threaded opening 11, the fourthinto threaded opening 12, the fifth into threaded opening 13, the sixthinto threaded opening 15, the seventh into threaded opening 16, theeighth extending under the body of the header through the space betweenthe legs 2. The opposite ends of pipes 31 and 32, 33 and 34, 35 and 36,and 37 and 38 are connected together preferably by similar couplings 39,the coupling for pipes 37 and 38 being omitted.

In practice, steam circulates in the direction indicated by the arrows,the steam being preferably produced from distilled water. In thedistillation process, vegetable gases Will be released and will rise tothe top of chambers 4, 5 and 6 and impose pressure upon valve plugs 30sufiicient to unseat the same and thus permit such gas to enter thechamber of the valve-casing and escape through passages 23 to theatmosphere, this action taking place, of course, if the pressurePatented Nov. 1, 1910.

of the gases exceeds that of the atmosphere, the sprlng 28 belng of suchpower as to reseat the Valve-plugs the instant the pressure of suchgases falls below that of the atmosphere in order to prevent airentering the said chambers 4L, '5 and 6. By the time the steam completesits travel through the coil it is condensed into water, which passesthrough pipe 38 to the freezing apparatus where, because freed of theobjectionable vegetable gases, it is frozen into solid cakes of "clearice Without a white core in the lower central part of the cake, whichcore is invariably found in cakes produced from water impregnated withthe vegetable gases referred to. Such core is not only representative ofa loss of good ice but contaminates water into which it is placed tosuch an extent that it is perceptible to the taste.

From the above description it will be apparent that I have produced agas-liberating header for steam-condensing coils embodying the desirablefeatures enumerated and which obviously is susceptible of modifica tionin form, proportion, detail construction and organization withoutdeparting from th'e'essential spirit and scope or sacrificing any of theadvantages of the appended claims.

c Having thus described the invention what I claim as new and desire tosecure by Let ters-Patent, is

1. In a steam condensing coil, a header provided with a series ofsuperposed chainbers and with gas-escape passages communica'ti11g 'wit'hthe upper ends of said chambers, the said passages of all of thechambers below the topmost one extending diagonally outward to one sideof the overlying chambers, hollow externally-threaded casings screwedinto said passages and provided at their outer ends with enlargementshaving radiating passages communicating at their inner ends with theinterior of said casings; said caslngs also having Valve seats at thelower or inner ends and perforated d1aciprocatory valves fitting in saiddiaphragms,

caps secured upon the upper or outer ends of v the casings, and springsarranged in the easings and bearing at their opposite ends against saidcaps and the valves and normally holding the latter upon said Valveseats to prevent the escape of gas, at less than a predeterminedpressure, from the upper ends of said chambers.

2. In a steam condensing coil, a header provided with a series ofsuperposed chambers and with gas-escape passages communicating with theiipper ends of said chambers, the said passages of all of the chambersbelow the topmost one extending diagonally outward to one side of theoverlying chambers, hollow externally threaded casings screwed into saidpassages and provided at their outer ends with enlargements havingradiating passages communicating at their inner ends with the interiorof said casings; said casings also having valve-seats at the lower orinner ends and perforated diaphragms outward of said enlargements, re-

ciprocatory valves fitting in said di'aphragms, caps secured upon theupper or outer ends of the casings, and springs arranged in the easingsand bearing at their opposite ends against said caps and the valves andnormally holding the latter upon said valve seats to prevent the escapeof gas, at less than a predetermined pressure, from the upper ends ofsaid chambers, in combination with a pair of pipes for and connected toeach of said chambers in different horizontal planes, and couplingsconnecting the opposite ends of the upper pipe of one chamber with thelower pipe of the adjacent superposed chamber.

In testimony whereof I affix my signature, in the presence of twowitnesses.
